To all whom it may concern) Be it known that l, lVILLIAM V. DARLING, acitizen of the United States, residing at Riverside, in county ofRiverside and State of California, have invented certain new and useful.Improvements in RoadwayllCflIll'lGl'S, of which thet'ollowing is aspecification. V

My invention relates to an improvement in roadway scarifiers, and theobject is to provide an apparatus which will cut away the thin or unevenportions of the surface of oiled or other roadways so that the usualroadgrader can follow and remove the cut away portions thereby leavingthe road in a smooth and even condition suitable for comiortable travel.

The invention consists of certain novel features of construction andcombinations of parts which will be hereinafter more fully described andpointed out in the claims.

In the accompanying drawings, Figure 1. is a view in elevation showingthe invention mounted upon a truck; Fig. 2 is a top plan view withcertain portions of l the truck broken away to show theinamter ofmounting the frame upon which the invention is suspended; Fig S5 is atop plan view of the invention; Fig. l is a transverse vertical sectinalview on the line 14 of Fig. 3.

A represents a wheeled truck upon which is mounted a frainell. Arectangular frame consistingoi two parallel angle iron bars C issuspended from the frame B by means of yolzes l, 1.

A plurality of axles 2 are journal ed on the bars (3 and are preferablymounted in journal boxes 3 which are connected to the bars C by bolts 4.Mounted upon the axles are a plurality of disks 5, 5, and l have shownthree disks mounted upon each axle although this number might beincreased, and supporting these disks are Washers 6. Nuts 7 having screwthreaded engagement with the axle 2 are screwed. against the outermostwashers (5 for fastening and look ing the disks upon the axles. Each setof disks overlaps the adjacent set.

Collars 8 are mounted on the axles between thenuts 7 and the bars C forproperly spacing the sets oi? disks between the hers,

and nuts 9 are screwed on the ends of theaxles for fastening the axlesof the journal boxes 3 to prevent lateral movement and for by providinga plurality of disks upon each axle and having them overlap each other,that is each set overlapping the adjacent set or the set carried uponthe axle in advance of the first set, the disks are capable of beingbrought into engagement with the surface of the road whereby the unevensurfaces of the road will be cut or broken up into small pieces so thatthe small pieces of the surface can be brushed or scraped irzun the roadsurface, yet these disks will not embed themselves into theroad andcannot be forced into the road surface as is the case With the usualroad grader forthc reason that the several disks being side by side oradjacent to each other, they could not he forced very deep into the roadhcd. And

vfurther, their staggered relation would not permit them to be used as amedium for removing the scarred or hroken particles from the roadsurface as would be possible with a road grader or sweeper. i It is theintention that the frame carrying the disks shall be shifted to anyangle dc sired, but under ordinary Working conditions it is generallycustomary to have the frame extending diagonally of the truck or vehiclecarrying the frame of disks.

Having thus described niy'invention, What I claim new and desire tosecure by Lettcrs Pa't el nt is- 1. In a road scarifier, thecombination. With a frame having a plurality of parallel axles journaledthereon, of a, plurality of disks mounted upon each axle forming a setof disks for each axle, each set of disks offset from the other sets sothat a disl; on each set lies adacent to one or" the disks of the set onthe axle in advance thereof, and the distance between the cutting edgesof a forward disl: and the dis-lit off a set which lies adjacent to thedisl; of the set on the axle in advance thereof is the same as thedistance between the cutting edges of the disks of each set.

2. In a road searifier, the combination wil'h a frame having a pluralityof axles journaled thereon, 01 a plurality of disks mounted on each axisand nested together so that the cutting edges of the disks will beprevented from embedding themselves in i i inmate the road surface, eachset of disks off-set disks of one .set with respect to the other, beingthe same distance apart.

- 3. In aroad scarifier, the combination with a frame consisting of twoparallel members extending diagonally to the line of draft of aplurality of parallel axles journaled in said-members transversely tothe line of draft, a plurality of concave disks contiguously arrangedmounted on each axle adapted to'travel in the line of draft said disksadaptedto, remove the uneven surface of the roadway without adecting thefoundation thereof and for loosening all the earth confined between theadjacent disks...

4. In:- a road scarifier, the combination avith a Wheel truck of a framesuspended therefrom, having axles journaled thereon, 3,..pl'urality ofdisks mounted upon each axle; said disks adapted to travel normally inthe line of draft, the disks of each axle traversing an area independentof the area traversed by the other disks, and means for actuating theframe carrying the disks, for moving the disks to-a position at an angleto the line of draft. v

5. In a road scariiier, the combination with a frame eonsistinggof twoparallel menihers extending diagonally to 'the line of draft, of aplurality'oitiparallel axles journaled in said ine'inhers' ltransverselyto the line of draft, a plnreil i'ty of concave disks contiguouslyarrangedl niounted on each axle adapted to travel ini the line of draft,said disks adapted to re'iiiove the uneven surface of the roadwaywithe'g it aifecting the foundation thereof and for loosening all theearth confined between the adjacent disks, and means for adjusting thedisks on each axle longitudinally thereof.

In testimony whereof I aifix my signature,

in the "presence of two witnesses.
